Diffrence between the physical properties of metals and non metals

Sure, here are the differences between the physical properties of metals and non-metals:

1. Appearance: Metals have a shiny appearance or luster due to their ability to reflect light. Non-metals, on the other hand, do not have a shiny appearance and are dull.

2. Hardness: Metals are generally hard. Some metals like sodium and potassium are exceptions and can be cut with a knife. Non-metals are generally not hard. For example, graphite, a form of carbon, is soft and can be used in pencils.

3. Malleability: Metals are malleable, which means they can be beaten into thin sheets. Non-metals are not malleable.

4. Ductility: Metals are ductile, which means they can be drawn into thin wires. Non-metals are not ductile.

5. Conductivity: Metals are good conductors of heat and electricity. Non-metals are poor conductors of heat and electricity. However, graphite, a form of carbon, is a good conductor of electricity.

6. Melting and Boiling Points: Metals generally have high melting and boiling points. Non-metals have low melting and boiling points.

7. Density: Metals have high density and are heavy. Non-metals have low density and are light.

8. Sonority: Metals produce a ringing sound when hit, so they are sonorous. Non-metals do not produce a ringing sound when hit.

9. State: Most metals are solid at room temperature, with the exception of mercury which is liquid. Non-metals can be solid, liquid or gas at room temperature.

10. Color: Metals are generally grey in color, with the exception of gold and copper. Non-metals come in various colors.
